HEADSET FOR TREATMENT AND ASSESSMENT OF MEDICAL CONDITIONS

NEUROLIEF LTD., Yokneam ...

1. A headset for use in delivering electrical stimulation to a skin surface of a head of a user, the headset comprising:
(a) a circumferential headset body, said body having a monolithic frame adapted to circumferentially fit around the head of
the user, said body housing an electric circuit adapted to be connected to a power source; said headset body including an
elastic arrangement, disposed on at least a portion of a circumference of said headset body; said elastic arrangement adapted
to be tensioned along said circumference;

(b) at least one electrode base, mechanically and at least semi-rigidly connected to said headset body, and electrically associated
with said electric circuit, said electrode base adapted to receive at least one electrode pad, and having:

(i) a housing including a floor, and a flexible circumferential member surrounding said floor, and having a flexible circumferential
wall extending generally above a perimeter of said floor, said wall ending in a circumferential rim; said floor and said flexible
circumferential member forming a cavity adapted to receive an electrically conductive electrode pad; and

(ii) an electrically conductive material, disposed at least partially above, or within, said floor; said conductive layer
adapted to be electrically associated to an electrical circuit, by means of an electrical conductor, and, when said pad is
inserted, to electrically communicate with said electrode pad;

said rim and said flexible circumferential wall adapted such that a pressure exerted against said electrode base, generally
perpendicular to said rim, and towards a skin surface of a user, urges said rim against said skin surface, to substantially
fluidly seal between said cavity and an ambient or external environment;

said headset body and said base adapted to orient an electrical stimulation surface of said pad towards the skin surface,
during donning by the user;

said elastic arrangement adapted such that, during said donning, said elastic arrangement radially urges said electrode base
towards the skin surface such that said electrode pad makes physical and electrical contact with the skin surface;

said elastic arrangement and said electrode base adapted such that for various degrees of tensioning of said elastic arrangement,
a circumferential position of said electrode base, with respect to said frame, is fixed in a specific predetermined position.

RESILIENT HEAD MOUNTED DEVICE FOR NEUROSTIMULATION AND SENSING OF BODY PARAMETERS

NEUROLIEF LTD., Yokneam ...

1. A headset comprising:an elongate body member configured to fully encircle the a head of a user, said elongate body member having a monolithic structure and having a rest state and a closed state and comprising:(i) an anterior section; and(ii) a pair of arm sections configured to be positioned above the user's ears, each arm section being flexible and resilient, and extending away from said anterior section and terminating in a posterior section which terminates in a posterior end;at least one size-adjustment mechanism configured to enable adjustment of the circumference of said body member to comfortably fit circumferentially about heads having different circumferences, at different times:
a closure mechanism associated with said posterior ends of said arm sections, said closure mechanism having an open position and a closed position, wherein, when said closure mechanism is in said closed position, said body member is in said closed state whereby said headset is fully circumferential; and
a processing unit,
a pair of posterior electrodes configured to be positioned against the skin of the head of said user, each mounted on an inner surface of one of said posterior sections, each posterior electrode of said pair being adapted to electrically communicate with the processing unit,
wherein, in said closed state of said headset, a distance between said posterior electrodes is fixed regardless of an adjusted size of said headset,
wherein the headset is configured, when said headset is donned on the head of the user, to urge said posterior electrodes to be positioned against the skin of the head of said user,
wherein said arm sections have a predefined preload such that when said arm sections are outwardly displaced, said preload drives said arm members toward each other, and
wherein, following placement of said posterior ends above the user's ears, while said headset is pushed rearwardly, said posterior ends are configured to apply a force to the head such that said posterior ends continuously engage the head.
